Corona 86

 1964-061A

---

CORONA 86 was launched on 1964 Oct 5 with a KH-4A payload. Mission 1011-1 was recovered on around Oct 9 after 85 orbits, with imagery of the USSR, China, Cuba and Zaire, but the SRV for Mission 1011-2 was not ejected; normal and lifeboat systems both failed. The inter-SRV fairing was confirmed to have ejected, but the SRV remained attached to Agena 1170, which reentered on Oct 26.

Mass of CORONA 86 was 1620 kg.

Discoverer 6

 1959-006A

Discoverer 6 reached orbit in Aug 1959 with a mass of 862 kg. Signals were not received after the capsule separation on Flight 6 (Mission 9003), and it is assumed the retrorocket failed,though what happened to the capsule afterwards is unclear.
